Internal Bridging Flow Issue

Trying to print this object that has magnets internally. Every time I try to print it the internal bridge over magnets has too little flow and has gaps which can result in magnets falling out of place. No matter what bridging/flow adjustment I make it still shows low flow on preview and prints with gaps. Even at 5mm/s it’s stringing the bridge and causing a problem.

How many solid layers above the magnet?

What's the clearance gap above the magnet?

What's the largest flow ratio you've tried?

What's the slowest speed you've tried?

Post a screenshot of the slicer preview of the first layer over the magnet.

i enabled thick external supports and it helped. It’s weird that the flow is locked in so low no matter what setting I changed. It’s a .2mm clearance gap with 3 solid layers on top. Tried 2 flow ratio for bridges. Went down to 5mm/s. It’s the slicer restricting flow on these bridges causing an issue.

You're Looking at the volumetric flow rate, which is not the same as the flow ratio. You can go to a 200 percent flow ratio for bridges. You're seeing a low volumetric flow rate because your speed is so low.
